This operation would block forever

I'm trying to launch lobby game after certain amount of time but I always end up getting error.

@dota.on('channel_join')
    def channel_joined(msg):
        nonlocal lobby_channel_id

        lobby_channel_id = msg.channel_id

        nonlocal match_started
        nonlocal count
        nonlocal max_time
        while count < max_time and not match_started:

            if count > max_time - 5:
                mod = 1
            elif count > max_time - 30:
                mod = 5
            elif count > max_time - 60:
                mod = 10
            else:
                mod = 30
            if count % mod == 0:
                dota.send_message(msg.channel_id,"Time remaining: " + str(max_time - count) + " sec")
            count = count + 1
            gevent.sleep(1)

        if not match_started:
            dota.send_message(msg.channel_id,"Starting the game! GL&HF!")
            dota.launch_practice_lobby()

Whenever dota.launch_practice_lobby() is called this error happens:

This doesn't look like problem with dota2 package. Hard to say what the cause is without seeing the complete code. Gevent might not play with certain packages, as the steam package makes use of the monkeypatching for stdlib.
